The impact of thermal treatment on the  granulometric and chemical composition of diatomite of the Kamyshlov field when obtaininga liquid-glass binder

Over the past few years, the Irkutsk Region has been included in the priority list of territories with the maximum degree of air pollution. In this case, the Atmospheric Pollution Index is used as the main criterion. In this work, the calculation of the complex index of atmospheric pollution formed during the operation of the heat supply system in the settlement of Listvyanka of the Irkutsk region is made. Heat consumers are multi-apartment residential buildings, public and business buildings. Heat supply of Listvyanka is carried out from four boiler houses. The API analysis showed that during the operation of the fuel and energy complex of small settlements, the degree of air pollution can be classified as “low”. Thus, the contribution of the fuel and energy complex to the total background air pollution can be considered insignificant.

The article solves the geometric task of constructing isometrics of the contour of spatial forms. The problem is solved by special construction of orthogonal projections of especial lines. These lines turn out to be contour lines of intersecting surfaces when they are further transformed into axonometry. Methods are considered to construct isometric contour of curved surfaces with finding their anchor points by superimposing projections of the same name. This simplifies the task of determining the coordinates of anchor points in a complex drawing.

This article contains an assessment of the effectiveness of innovative solutions in the construction of oil and gas wells. Despite the fact that the oil and gas industry is not knowledge-intensive, quite conservative in the implementation of innovations and gives a large share to the federal budget, it is designed to increase competitiveness and ensure sustainable development of the country’s economy. The introduction of innovative solutions is designed to increase the company’s revenues, reduce the cost of production, reduce operating costs, and increase the company’s competitiveness and image. They help to maintain existing market positions and conquer new market segments. Among the most promising technologies that are actively used in the construction of oil and gas wells, a special place is occupied by the use of “digital twins”, which are modern digital models of objects. Such a model most accurately reflects the real condition and performance of its physical prototype. No matter how precise, detailed and elaborate the actions will be at the design, modeling and production preparation stages, during operation, as a rule, the processes proceed a little differently, and the digital twin is able to be the main access tool to the necessary information about the actual operation of the facility.
